A/N Thank-you to mischief-manager00 for BETA reading this story :)

Castle liked to think of himself as someone who could run faster than anyone else, knock suspects off their feet before anyone else had even caught sight of them, and shoot the gun out of someone's hand without hitting them, basically a superhero. In reality, he was lucky that he could keep up with Beckett let alone catch a suspect without so much as a bruise.

It's this thought process that led Castle to the roof of his building, clad only in his Batman boxers, red blanket tied around his neck and rambling on about saving the world from a plague of evil Furbies.

24 hours earlier…

Their suspect rounded the corner into an alleyway, running for all he was worth, Beckett and Castle hot on his heels. Their feet pounded the pavement, sweat glistening on their bodies as their breaths came out in short gasps but they kept going. He couldn't run forever. Technically they had already ran 12 blocks past forever but who was he to judge?

The man they were chasing was your average, run of the mill street drug dealer, his specialty being LSD. In other words, he was a scrawny young man with little brains, what little he did have filled with the recipe for the drug in question. He couldn't be that hard to catch, right?

The chase led them further into a district of abandoned, fire bombed buildings worth little, if not nothing, to anyone. Except apparently the suspect who led them into an abandoned warehouse with all but one of its windows smashed and floor's covered in trash. As they entered the warehouse they were greeted by the pungent smell of ammonia. It was defiantly a drug lab. Castle's lungs burned with each breath and yet he still managed to call the guy an idiot. He had inadvertently led them straight to his lab. For someone that dumb he was pretty fit Castle thought as he stopped to catch his breath, leaving the suspect for Beckett. He spotted some sugar cubes on a plate in the middle of the bench and not at all suspicious of this, his inner child rearing at the thought of the sweetness and sugar rush that would accompany it, he plucked some, putting them in his mouth hoping to gain some energy…

Beckett was gaining on the suspect as he kept turning to look behind him. She eventually got close enough to take a flying leap onto him, knocking all the air from his lounges. Wasting no time she slapped the cuffs on him before calling for a team to go over the place with a fine tooth comb. She would find evidence that he was the killer and if not at least there was one less drug dealer off the streets. It was a small victory but enough, at least for the day.

Once forensics had gone over the building, indeed finding a drug lab and Beckett had briefed the captain, she was more than ready to go home. Walking off, she found Castle outside, looking up at the sky with a somewhat distant look in his eyes. Suddenly he whipped around and shouted;

"The Furbies did it!"

Beckett's eyebrows rose skyward. She was used to Castle coming up with some pretty crazy theories but this was insane, even for him. When he got no reaction from her, he turned around and attempted to jump over a police car, falling of the hood and failing miserably. He now had the attention of everyone on scene.

"Dude, are you ok?" Esposito asked, watching the author who was currently hiding behind the car, occasionally peeking out. He then proceeded to roll, mission impossible style out from behind the car, landing on Beckett's boot clad feet. She looked down at him, concern covering her face.

"You're pretty" he said, whatever he had been doing before now long forgotten,like an absent minded child.

"Are you sure he didn't accidently get dosed with something?" Ryan suggested, earning a few nods from his colleagues. Castle was now back on his feet and circling Beckett who, to her credit, only looked slightly terrified. Castle was a five year old on a sugar rush as it was. With drugs in his system well, that was a scary thought.

"My precious" he stated before enveloping her in a tight hug from behind.

"Castle" she hissed in surprise, her eyes flashing dangerously.

"Hey dude, chill" Esposito said, walking up to Castle but stopping when he growled. This was not normal. Why couldn't he just space out like everyone else who got high?

"Um Castle, could you please let go? I can't breathe" Beckett said, her face beginning to turn purple.

Castle seemed amazed by this new development.

"I didn't know you could turn purple" he said, releasing her and walking around to face her.

"Do it again" he said, eyes shining like a child with a new toy.

"Uh, no" she replied, walking over to Esposito and Ryan.

"I'm going to take him home and keep an eye on him since Alexis and Martha aren't there" she said. "Can you two handle things here?"

"Yeah, sure" Esposito replied.

"Ok Castle come on, we're going home now" she called as she turned around to find him standing on the roof of a patrol car, fascinated by the lights.

He turned to her and asked "Can you pleeeeeeeeease turn them on?"

"No" she said, walking to the Crown Vic that she had brought around earlier. Castle merely looked at her, wide-eyed.

"Castle, get in" she said firmly.

"No" he huffed, making no effort to get down.

She sighed and pulled out a Snickers bar, tossing it in the car. Castle scampered down and couldn't get in fast enough. Beckett got in, locked the doors and did up his seat belt while he happily munched on his snack.

By the time they got back to his loft Beckett was ready to shoot Castle. Or herself. He had been going on and on about something but she had stopped listening, instead choosing to focus on the road. It took all of 10 minutes just to get him up the stairs and into the loft after he refused to take the lift, screaming in the middle of the lobby when she tried to shove him in. Once he was safely inside and sitting in front of the TV watching Young Justice, she locked the door and sighed in relief. She looked over at him to find him lying across the couch, feet hanging off the armrest fast asleep and snoring softly. She smiled to herself. He did look kind of cute like that. She fetched a blanket and gently laid it over his sleeping form. He looked uncomfortable is his current position but the last thing Beckett wanted to do was wake him up so she let him be, casting one last glance at him before retiring to the guest room.

She was woken from her blissful slumber by the sound of someone yelling;

"They're taking over, praying on innocent children's souls. I have to stop them!"

She glanced at the bedside clock, finding that it was 2 in the morning. She had barely been asleep for half an hour. She groaned and rolled over. The sound of the front door being wrenched open and slammed shut had her out of bed and out the door in 10 seconds flat.

She followed Castle's form all the way to the roof. Since when could he run that fast? She wondered as she stepped out into the cold night air. Castle was standing in the middle of the roof, clad only in Batman boxers with the red blanket that she had covered him with earlier tied around his neck, yelling like a complete maniac.

"The Furbies are taking over! Only I can save your helpless souls" he screamed.

She stared at him for a full minute before interrupting his ramblings.

"Castle, what the hell are you doing?" she asked the delusional author.

He turned around to look at her. She sensed a shift in his mood right before he started yelling again.

"Aha, a damsel in distress. Every superhero has a love and you shall be mine!" and with that, he strode over to her and kissed her. On the lips. Hard.

She stood in stunned silence, her brain unable to process this new development. He pulled away, smiling triumphantly.

"Lost for words?" he asked, smirk firmly in place. She glared at him. And the day ended with her dragging him by the ear to bed.
